We have a bitmap index AM in Bizgres (on PG 8.1.3) that is functional and
achieves very worthwhile (10x+) performance and space objectives.

the appropriate executor nodes.  The latter part was necessary because of
the need to bypass the in-memory bitmap index when an on-disk bitmap is

Because this patch is large, how do you suggest we go through review?  Also,
there is some further work that Jie is doing to support efficient
multi-column indexes that will simplify the code, so we're not quite ready
for patch submission.
